* One object of thepresent inventioni'sthejpro- 5 vision of a novel elongated spring separator for rolling mill chocks which enables the use; of antifriction bearings for the necks of. the rolls lofa mill.,,

, Another object is the provision of a novel d'e vice of theflclass described which will be .cheap and easy to .manufacture and will ,jre'quire no adjustment or replacement while in service. I These and further" objects will"'b'e apparent after. ref erringto thejdrawings, in which:

Figure 3 is a, fragmentary front elevation, partly in section, of the mill of Figures 1 and 2.

Figure 4 is a perspective view of the novel spring separator of the invention.

Referring more particularly to the drawings, the numeral 2 designates a housing for supporting the rolls of any of the well known types of rolling mill.

The housing 2 supports on both of its sides a pair of chocks 3 in vertical juxtaposition, and which are adapted for vertical movement with cured to the housing 2-by means of bolts 5 for maintaining the chocks 3 from moving. sidewise' bottom of the chocks 3 are moved vertically by,

means of the usual wedge-adjuster, generally indicated at II. g

The adjoining edges of adjacent pairs of chocks 3 are each provided with convexed mid-portions l2, intermediate flat portions occupying a, common plane at right angles to the vertical center line of the housing 2, and a concavity adjacent each of its ends.

The novel elongated spring separator for resiliently maintaining the chocks 3 apart is generally indicated at ,l5 iandisprovided on its upperand lower mid-portions with a concavity l6 conform ing closely to thec'onvexed mid-portions of the adjoini g, edges. of. the chocks. The intermediatefl portions of the elongated. spring separator H; are provided,with..'flat surfaces, l'l conforming substantially. to the intermediate surfaces of the chocks While the. extremitieshthereof are T eachprovided with anupper and lower convexed portion l8 conforming closelytothe concavities id of thei ch'ocks and cantilevered from: the main or mid-po'itionof the separator 15, thus leaving a 'sl'otf [9f between the upper and lower convened jpor'tion'sflfl to allow for spring deflection when the 11111 rolls and ocks rg chaser tb t r; a

In installation, the lower of the chocks 3 on contour generally similar to the adjacent surfaces of the chocks, are maintained in spaced relation thereto, so that the only "contact between the separator and chocks is at the ends l8. The space or clearance between the aforesaid surfaces must be less than the maximum allowable deflection of the cantilevered ends 18 of the separator I5;

As the screw 3 and wedge adjuster generally indicated at H are adjusted, the various chocks will be moved relative to each other and resiliency established between them at points adjacent their ends. This relationship is maintained, of course, until such adjustment is made as will cause the rolls to bebrought to the desired position. The roll collars will be in contact before the chocks come in contact with the mid-portions of the spring separator l5, and of course before it has reached its elastic limit.

Due to the convexed mid-portions l2 ofthe chocks 3, a sufficient cross-section of metal is permitted at the centers thereof to permit the use of roller bearings, which are recognized as being decidedly superior over the usual brass type of bearing, while a resilient influence is exerted by the spring separator to maintain the chocks '3 and accordingly the bodies of the rolls 1 out of contact. There are, however, many mills employing the usual brass type of bearing which render ver'ysatisfactory service, and the device of the invention may be easily adapted thereto.

While I have shown and described one specific embodiment of my invention, it will be understood that I do not wish to be limited exactly thereto, since various modifications may be made without departing from the scope of my invention, as defined in the following claims.

I claim:

1. A spring mounting for heavy elements normally free and tending to move toward each other comprising, in combination, a pair of opposed blocks for supporting said elements, the adjoining edge of each of said pair of opposed blocks hav ing a concavity adjacent each of its ends, and a: spring separator adapted to be placed between the adjoining edges of said: blocks and having upper and lower cantilevered convexed portions at each of its ends conforming substantially to the concavities therein, said spring separator beipg disposed in such manner as to cause-the lower cantilevered convexed portions a t: each of itsendsto occupy the cancavities of said pair of oppqsed blocks while the remainder oi the spring separator and the remainder of the adjoining edges of said blocksare maintained in spaced relationship, with respect to each other. 2. A spring mounting for heavy elements normally free and tending to move toward each other, comprising, in combination, a pair of opposed blocks for supporting said elements, the adjoining edge of eachof said pair of opposed blocks having a concavity adjacent each of its ends, the mideportion or the adjoining edge of eacli of; said pair, of; blocks having a convexity and'a spring separator adapted to be placed between the adjoining edges of said blocks and having upper and lower cantilevered convexed portions at each of its ends conforming substantially to the concavities therein, said spring separator being disposed in such manner as to cause the upper and lower cantilevered convexed portions at each of its ends to occupy the concavities of said pair of opposed blocks, the mid-portion of said spring separator having a concavity on each of its sides to conform substantially to the convexities of the mid-portions of the adjoining edges of said pair of opposed blocks, thus providing for close adjacency of the blocks and spring separator and the maintenance of a spaced relationship therebetween except for the end-portions thereof. 7 3. A spring mounting for mill rolls which are normally free and tending to move toward each other comprising, in combination, a pair of opposed blocks for supporting said rolls, the adjoining edge of each of said pair of opposed blocks having aconcavity adjacent each of its ends, and a spring, separator adapted to be placed. between the adjoining edges of. saidv blocks and having upperand lower cantilevered convexed portions at' each of, its ends conforming substantially to the,concavities therein, said spring separator. being disposed in such manner as to causetheupper and lower cantilevered convexed' portions at each of its. endstooccupy the concavities of said .pair of opposed blocks While the remainder of the spring separator and the remainder of the adjoining edges of said blocks are maintained in spaced relationship with respect to each, other.
